The submarine now had come against the half concealed dock that had caused the castaways such wonderment when they approached the shore. At command of their captors, they leaped to the deck of the submarine and then passed through the conning tower and descended below.

At sight of the interior Frank could not suppress an exclamation of astonishment. The vessel was fitted with the handsomest of appointments. The little cabin into which the three prisoners were led even showed signs of an artistic taste, undoubtedly that of Captain Jack, Frank thought.

"This young pirate certainly has an eye for the beautiful," Frank told himself.

The prisoners once inside the cabin, the captors withdrew and locked the door behind them.

"Well," said Frank, "here we are, men. What are we going to do about it?"

"Nothing we can do, sir," said Allen. "He will probably offer us a chance to join his crew and if we refuse he'll heave us all overboard."

"I'm a f raid he'll have to heave away then," said, Frank, "for I don't think I would make a very good pirate."

"I'd make a better pirate than I would a corpse, sir," declared Timothy, "and this fellow must have made quite a success. Here he is the undisputed owner of a submarine fitted out like a palace; he's his own boss and his prizes he probably distributes among members of the crew. Why, sir, a year of this life and a man would be rich."

"Look here, Timothy," said Frank, "I don't like that kind of talk.
Why, man, you talk like you would like to be a pirate."

"Maybe I would, sir. I've thought about it for years. Look at the excitement a man could have."
